Procedure

Configuring the RAD-900-IFS wireless modules for PLC Mode communication

1. Set the yellow thumbwheels of the three RAD-900-IFS modules to 01, 02 and 03 and reference the data

sheet for power connections. Set the white thumbwheels of the RAD-DAIO6-IFS modules to 01 and 02.

Connect the RAD-DAIO6-IFS modules to the RAD-900-IFS modules via the TBUS connectors supplied in the

box. The RAD-DAIO6-IFS module with thumbwheel setting 01 should be connected to RAD-900-IFS module

with yellow thumbwheel setting 02. The RAD-DAIO6-IFS module with thumbwheel setting 02 should be

connected to RAD-900-IFS module with yellow thumbwheel setting 03. Apply power to all three wireless

modules.

2. Open PSI-CONF 2.60 and select the 900 MHz selection under the Wireless tab. Click ‘Next’

3. Click on ‘New’

4. Select ‘Point To Point / Star’ and click ‘Next’

5. Set the number of slaves to ‘2’ and click “OK’.

6. On Wizard, Step 2, confirm information is correct and click ‘Next’.

Page | 5



7. On ‘Wizard, Step 3’, select ‘PLC/Modbus RTU mode’ in the ‘Application of wireless network section’. Leave

the Modbus address at 1. In PLC mode, the Modbus address will function as a single Modbus ID for the entire

wireless network. For a simple bench test the rest of the settings can be left unchanged, but depending on the

environment that the system will be installed in the “Network Settings’ and ‘Network speed/distance relation’

settings may need to be adjusted. Click ‘Next’

8. On ‘Wizard, Step 4’, leave the settings at default and click ‘Next’.

9. On ‘Wizard, Step 5’, review the data and click ‘Next’

Page | 7



10. On ‘Wizard, Step 6’, make sure your programming cable is connected from your computer to the wireless

module with Yellow thumb wheel setting '01’. Click ‘Transfer’ to send the configuration to the wireless

modules. You will be prompted to save your configuration. Choose a file location to save your program.

11. When prompted, click ‘OK’ to go online to the wireless module

Page | 8



12. Click on ‘Start Transfer’ under ‘Local Transfer’ to send the configuration to each device. Once you transfer

the configuration to one wireless module, move your programming cable to the next wireless module. The

Transfer Window will show you which module you are connected to and which modules have had the

configuration transferred.

Page | 9



13. Once you have sent the configuration to each wireless module, the wireless network configuration is

complete. The RF Link LEDs on the wireless modules should illuminate. On the master wireless module

(Yellow Thumbwheel on 01) should have one amber LED illuminated (assuming there is more than one slave

wireless module in the network) and depending on the antennae on the slave wireless modules, there should

be an amber and module green LEDs illuminated. Red ERR LEDs will be flashing at this point since there is

no Modbus communication.

The wireless network configuration is complete and is set up for PLC Mode communication.

Configuring the GW EIP/MODBUS 1E/1DB9 module for Modbus RTU to EtherNet/IP

communication

1. The GW EIP/MODBUS 1E/1DB9 comes with a default IP address of 192.168.254.254. Set your computer’s IP

address in the same network as the GW EIP/MODBUS 1E/1DB9 (192.168.254.XXX). Reference the data

sheet for power connections and apply power to the GW EIP/MODBUS 1E/1DB9.

2. Log into the GW EIP/MODBUS 1E/1DB9 by browsing to the default IP address of 192.168.254.254 (accept any

warnings that may pop up in your browser) and using the default User Name and Password

a. User name: Admin

b. Password: admin

3. Verify the serial port settings of the gateway match the serial port settings of the master Radioline unit (the

default serial settings of the gateway should match the Radioline settings, but double check to make sure.)

Click on the ‘Serial Settings’ tab. The next screen will show you the settings, verify Port 1 is set to RS-232,

19200, 8, none, 1

Page | 11



Click on the ‘Port 1 Configuration’ tab and set the ‘Serial Device(s)’ drop down to ‘Modbus RTU Slaves’. This

tells the gateway it will be talking to a Modbus slave device. Click ‘Apply Changes’.

4. Click on the ‘Data Mapping Settings’ tab and then the ‘Modbus to Tag/File’ tab. In this section we will

configure the Modbus communication from the Radioline wireless network to the EtherNet/IP master (Modbus

to EtherNet/IP). In the example below, we are reading from Modbus ID 1, the 30012 and 30022 registers and

pointing them to a Tag of “Radio1_input_data’ and “Radio2_input_data’ which are configured in a

ControlLogix PLC at IP address 192.168.1.101

.

For this step you will need the following information:

For the Modbus device:

The Device ID of the Modbus device

The Function code for the Modbus communication

The Modbus register address and length

For the EtherNet/IP device:

The PLC type

The IP address of the PLC

The Data type

The Tag/File name

Click ‘Apply Changes’ once you have entered all of the information

Page | 13



5. Click on the ‘Data Mapping Settings’ tab and then the ‘Tag/File to Modbus’ tab. In this section we will

configure the communication from the EtherNet/IP master to the Radioline wireless network (EtherNet/IP to

Modbus). In the example below, the gateway is receiving a command from the ControlLogix PLC at IP

address 192.168.1.101 and writing to Modbus ID 1, the 40012 and 40022 registers and pointing them to a

Tag of “Radio1_output_data’ and “Radio2_output_data’ which are configured in a ControlLogix PLC at IP

address 192.168.1.101.

For this step you will need the following information:

For the EtherNet/IP device:

The PLC type

The IP address of the PLC

The Data type

The Tag/File name

For the Modbus device

The Device ID of the Modbus device

The Function code for the Modbus communication

The Modbus register address and length

Click ‘Apply Changes’ once you have entered all of the information

The configuration for the GW EIP/MODBUS 1E/1DB9 is now complete.

Configuring the Rockwell PLC

In your RSlogix project you will need to create variables under controller Tags that exactly match the information

from Step 5. For example for “Radio1_output_data” you will need to enter the following information.

Tag/File name: Radio1_output_data

Data type: INT

Dim0: 2 “length of array needs to match the length of the read multiple registers call”

External access: Read/Write.

You will need to create variables in your RSlogix project for each variable you created in Step 5.

Making the physical connections

In this setup, there are three stations, the master station, slave station 1 and save station 2. Connect an antenna

to each wireless module and make the physical connections for the data cables and I/O modules for each station

shown below.

Master Station

1. Connect a RJ45 cable from the PLC to the GW EIP/MODBUS 1E/1DB9 with IP address 192.168.254.254.

2. Connect a Straight through RS232 cable from GW EIP/MODBUS 1E/1DB9 to RAD-900-IFS with yellow

thumbwheel of ‘01’.

Slave Station 1

1. Verify the RAD-DAIO6-IFS module with thumbwheel setting 01 is connected to RAD-900-IFS module with

yellow thumbwheel setting 02.

Slave Station 2

1. Verify the RAD-DAIO6-IFS module with thumbwheel setting 02 is connected to RAD-900-IFS module with

yellow thumbwheel setting 03.

Your setup is complete, and you are ready to verify communication. Your network layout should match the

drawing below.

Disclaimers and notes

1. The purpose of this document is to provide basic configuration settings to show communication. Each

application has different requirements and those need to be discussed before implementing any solution.

2. The setup described in this document uses a default PLC configuration. The PLC configuration will be

different from application to application.

3. This setup was a point to multi-point setup in a bench test environment. The addition of repeaters and RF

interference can cause added latency and should be expected. If there are concerns about these items a

temporary installation should be tested.

4. The installation of these components in a real application is at the discretion of the user.
